Serial Output Stream
The sequence below shows how the slot outputs are scanned out in order. If the board implements
less than six slots, then the serial input bits corresponding to those slots are arbitrary and are
ignored by the Intel® 6702PXH 64-bit PCI Hub.
Every round of polling by the Intel® 6702PXH 64-bit PCI Hub involves shifting all 36 bits,
regardless of the number of slots implemented. Bit 1 in Table 2-26 represents the first bit that
shifted into the Intel® 6702PXH 64-bit PCI Hub in the sequence of 36 bits.
